The Lost Sun

Summary: It's been three years since the Giant War. It's been three years since peace was brought. And it's been three years since Percy Jackson disappeared. They searched and searched, but never found him. Now, Artemis has been assigned to hunt down a man with white hair and bring him to Olympus. Who is this man? Why do the gods seek him out? "O' Agni…"

Crossovers: Fate/Series + Percy Jackson and the Olympians

"By my authority as King, I call this meeting of the gods to order!" Zeus' voice boomed throughout the throne room of the gods to order. The room glowed a brighter gold, as if acknowledging the King's words.

"Today, I bring forth an order of business regarding the recent disappearance of monsters," Zeus said, prompting many confused looks. "As of late, monsters have been dying far more often than usual. Furthermore, they have not been killed by our own children, or Artemis' hunters."

"What's the problem with that?" Ares asked, sounding bored. "Shouldn't it a good thing something is taking care of the monsters for the little brats?"

"Ordinarily, yes," Zeus agreed. "But that in itself presents an issue of WHO has been doing this, and so efficiently. I called this meeting so suddenly because the mortal managed to escape Iris' eyes, and the only time we can view him in combat."

That surprised many of the gods. That someone who was allegedly mere mortal could avoid Iris' attempts to find him was nothing short of incredible.

"Who could be such a person, father?" Athena asked, clearly interested in who could avoid Iris for so long. She was only second to Apollo when it came to sight.

Zeus waved a hand as a Rainbow appeared. "We shall see," he told her. "Iris, show us the man." He said firmly, and the Rainbow shimmered before they got their first look at the man who had been killing all of the monsters so quickly and efficiently.

The first thing they noticed was, of course, that he was in combat against an entire army of Hellhounds in the middle of the Arizona Desert.

The second thing they drank in was his appearance. He was fair skinned, quite pale even. His hair was also a beautiful, clean white that almost seemed to twinkle in the sunlight. He was dressed in thin black clothing, and golden armour adorned the entirety of his body. Hanging from his neck was a red jewel, and he wore a cloak of purple that wavered and twisted as if it were living fire. On his left ear was an earring, beautiful enough to make Aphrodite squeal at the sight of it.

The last thing they looked at was the weapon in his hands, and it left Hephaestus himself awestruck at the beauty of it. A golden spear, the work of which could have definitely only come from the gods. It was a work of art, something that was nothing less than exquisite to look at.

What caught the gods by surprise was that the man abruptly stopped moving for a moment as he pierced a hellhound with his spear. He turned his gaze, looking straight through the rainbow and at them. The man said nothing, simply staring at them. And they in turn couldn't help but stare at his eyes.

Green. They were the most exquisite shade of sea green the gods had ever seen, and even his face was more handsome than they could believe. Several of the goddesses blushed as they saw him, even a supposed virgin in Athena.

So caught up in staring at him, they were caught by surprise when a hellhound bit his arm. They expected him to at least dodge, or to turn away and yell in pain. Instead, they were taken by surprise as the fangs of the hellhound barely pierced his skin. The man looked down at the beast that bit him, before his spear flashed out and pierced the evil being through its skull. It turned into gold dust.

"I grow tired of this," the man finally said in a soft voice, jumping back away from the monsters. "I hereby sentence you to Tartarus. Rest there for at least a century." With his piece said he simply fell to one knee and held his hands together, as if he were praying.

The monsters took the chance and all jumped at him, fangs out and claws sharpened, ready to take his life. The Gods watched as the monsters all piled in top of him, and surely killing him.

"O' Agni…" That soft voice came, and a pillar of flames shot up and consumed both the hellhounds and the man beneath them. Roars and screams of agony came from the beasts. And within moments, the flames cleared.

He stood unharmed, spear in hand, and all around him the hellhounds were nothing but golden dust. He rested his spear on his shoulder, and began to walk away. Before he paused, turning back and looking at the gods.

"It is impolite to watch people when they are busy working," he spoke, as if he knew they could hear him, and as if he could hear them in turn. "I know you will send someone after me, but I do not blame you. I cannot be left unchecked, after all." And with that piece said, flames burned around his form; and by the time he cleared, he was no longer there.

The image on the rainbow blurred, as if trying to track him, but after a moment or so, Iris appeared in the rainbow instead and shook her head. "I apologise, Lord Zeus. But I just cannot track him, and I simply cannot understand how."

"It is fine Iris," Zeus said, waving the rainbow away. He redirected his gaze to the other gods. "As you can see, this mortal is very dangerous. His skin appears to be so tough that he takes little damage, his spear seems to be made entirely of pure Imperial Gold, and he has power over fire. We cannot just leave him wandering around unchecked. Which is why he needs to be brought here to swear his loyalty to Olympus."

"But father, that sounds like what he wants," Athena said to him analytically. "He said that he knew we'd send someone after him, what if this is a trap we are walking into?"

"We don't really have much of a choice," Hermes pointed out. "Trap or not, we kinda have to bring this guy in. I'm in agreement with pops, too much power to left go unchecked."

"I'll go pick him up!" Ares declared, a grin on his face.

"No," Zeus denied immediately. "For one, you won't be able to even find him. If he can avoid Iris of all people, you stand no chance. Artemis, you shall hunt him down and bring him here. Alive. You may use force if needed, but he is to be brought here alive. And preferably not castrated."

Artemis grinned wickedly. Sure castration was off the table, but she could do many things to a boy. Many horrible, awful things. "Very well, father. It shall be done."

"Artemis…" A weak voice came, and everyone's gazes immediately swept to the speaker with an almost pitying look.

Poseidon seemed to have aged several millennia once Percy went missing three years ago. His hair was an ashen white, his skin so pale that he could have been mistaken for a ghost. Where once his sea green eyes showed joy, they were now empty and almost dead. It had taken many talks for Poseidon to even reach this state. He was much worse only a year ago.

"Yes, Poseidon?" Artemis asked carefully. Dealing with Poseidon was now dealing with a minefield.

"If you get any word of Percy… Please…" His voice was soft, almost broken. It was painful for any of the gods to see the once proud God of the Seas in such a horrid state. It wasn't just that Percy had gone missing, but that not once in three years had Percy touched his domain. Not a lake, not a river, not the sea, not an ocean. It hurt Poseidon that his own son, his greatest son, his pride and joy, would no longer want to touch water.

"I will inform you immediately, uncle," Artemis said. "Is there anything else that is required, father?"

"Nothing pressing," he said. "You may go, daughter. And… Be careful."

"Yes, father," Artemis nodded before she vanished into a silver light, returning to the hunt.

"My lady," Thalia greeted her within moments of her return. "Might I enquire as to what the meeting on Olympus was about?"

"We are going on a hunt," she said to Thalia.

"What kind?"

"A boy hunt."

Immediately, Thalia's lips spread into an almost bloodthirsty smirk. "I will inform the hunters to break down camp at once, milady," she said, hurrying away to inform the hunters of their newest mission.

Artemis nodded, and went to deal with her own tent. Yet she couldn't shake a strange feeling…that this hunt would be different than the others.

-Line Break-

It had been three days since Artemis and her Hunt were sent to find the white haired man and bring him back to Olympus, by force if needed.

It hadn't been easy tracking him. The only times they were able to try to do so was when he ended up fighting monsters, and they were lucky enough to find a few drops of blood that could be followed by their wolves. But they would always lose the scent, and it was incredibly frustrating.

But on the second day, the man… Stopped. Impossibly, they found him simply sitting in a clearing on top of a log. His legs were spread slightly as he sat, and his hands were pressed together with his eyes closed. His spear was stabbed into the ground next to him, ready to be drawn at a mere moment's notice.

Some of the hunters wanted to move in and apprehend him, but Artemis stopped them, feeling weary about such a relaxed state. Instead, she left Thalia and Phoebe to observe him while the others set up Camp nearby. The orders were obeyed, and Artemis began to organise a battle plan to apprehend him; she was confident he'd try to fight back to save himself.

She decided to wait until the fourth day before moving in, having some hunters rotate in watching him to be sure he didn't move. After all, it wouldn't do to lose their prey so soon after finding him.

And yet, what she learned from her hunters honestly surprised her. The man had no moved so much as an inch for his positioning, only breathing in and out as he seemed to have slept all day and all night. He didn't even wake up to go and eat, or to run away. He just stayed there, fast asleep and ignorant of his fate.

Still, she didn't question her good fortune. Having seen what he could do with people surrounding him, Artemis had the majority of the hunt at the distance, and only seven hunters walking towards him with her.

As soon as they stepped into the clearing, his eyes slowly opened. "I have been expecting you, Lady Artemis," his soft voice came. What irked Artemis was there was no arrogance present in his voice. No haughtiness, nothing to suggest he was boasting. He simply stated it as if it were a fact, like he'd been expecting her to be here at this time.

"Is that so, boy?" she asked, holding an arrow towards him. "Then do you also know that, by the order of Zeus, you are to be brought forth to Olympus?"

"I am aware," he said. "And I have no intentions of fighting back. I shall let you take me in peace… But first…"

"First what?" Thalia demanded, eyes narrowed.

In response, the man simply jutted his thumb behind him. "I have an old score to settle with someone, one last time. I ask you to allow me to settle my score with the beast that is coming peacefully."

Artemis' eyes narrowed. "And why should I do that?"

"You do not. It is simply a request," he told her. "But it is my hope you understand one's desire to face someone and settle the score. After all, I doubt you yourself would be satisfied if you were tied in wins and losses to Athena in combat."

That made Artemis falter. Curse him, he made a good point. She would absolutely hate if she and Athena were tied in wins and losses in combat, it would be awful because she'd want to have that nice little extra point that cemented her victory over her sister.

"Fine," she growled. "Hunters! Pull back!"

"But my lady!" Phoebe tried to complain.

"If he is about to die, we shall step in and kill whoever he is fighting, and bring him back to Olympus regardless," Artemis told her.

"You have my thanks, Lady Artemis," he said, having never once looked up at them. Instead, he slowly rose to his feet as the hunters and their goddess backed up. He turned, and a roar was heard as a beast marched out of the forest. One that had Artemis' eyes widening.

Half-man, half-bull. Armour covering its body from the waist down. An axe in the shape of a Greek Omega. The beast the man wished to face alone was the Minotaur.

"You've been chasing me for nearly a year," he told the beast, his hands not even going to the spear. "You can smell it, can you not? My stench, the stench that you hate so much, more than any demigod or god. Above all else, you cannot stand the fact that you have lost to me not once, but twice."

The beast roared loudly, as if confirming his words. Artemis could see nothing but pure hatred in the eyes of the Minotaur as it stared at the young man. There was some kind of grudge, and Artemis didn't understand. Why did the beast hate the man so much?

"We settle this, once and for all, right now," the man finally said, his hands still not going to his spear. "This shall be the final time we face off against each other, beast. As strange as it sounds, it has been an honour to face a beast such as yourself in combat. And out of respect for your determination, I shall strike you with one of my strongest attacks."

The Minotaur roared and began to charge at the man, and still he did not reach for his spear.

"What are you doing!?" Thalia yelled. "Use your spear you moron?"

The man looked back, and gave a soft smile. One that made Artemis' heart stop as she saw another face overlap with that of the man's. Those sea-green eyes, that gentle twinkle in them… They were all just like someone else's. Someone very familiar to the gods.

"Weapons are inadequate," he told Thalia, his left eye turning into a blazing red as he looked back towards the Minotaur. "A true hero can kill with only a stare," unseen to them, something sparked in that crimson eye that stared at the Minotaur. "Brahmastra!"

With that one word, destruction followed. From his eye, a beam of energy surged forth, enveloping the Minotaur. There were no screams, no spoils of war, nothing. Only raw power that shot forth, enveloping the Minotaur and anything that was in the way of the blast. It travelled on… On… And when the crimson energy finally died, a path of destruction and scorched Earth was all that remained from the attack.

Artemis and her hunters were speechless at the sight of the man killing the Minotaur, a powerful beast in its own right, with only his stare.

Turning around, he pulled his spear out of the ground, placed it upon his back. With that, he stepped forwards, offering his wrists. "You may take me now," he told Artemis. "To Olympus."

Artemis was quick to recover, unlike her hunters, and placed the man in the Celestial Bronze cuffs to seal away his powers. "Return to the camp," she told the seven girls. "I shall be taking this man up to Olympus for questioning."

They all hurried to nod and rushed away to the Camp to follow their ladies orders. They would no doubt also tell the other hunters to return as well.

"How nostalgic…" He said softly to himself, though Artemis still heard him, and chose to ignore him as she flashed them up to Olympus.

-Line Break-

'How unpleasant,' the man thought to himself as they were flashed up to Olympus. Perhaps for the gods, it was an ideal form of travel. But for a mortal such as him, it was like he was turned upside down and then flipped right side up, all in a split second. And then all the motion registers once a further two seconds have passed, and it hits all at once. It took all he had not to throw up. To his credit, he only stumbled slightly.

Artemis raised a hand, finger glowing with sliver light that shot up. Moments later, the man was greeted to the sight of the Olympian council. 'Ah, how nostalgic…' He thought to himself for the second time that day.

His eyes then landed on Poseidon, and it took all he had not to flinch at the sight of the man. He appeared to be a wreck, he looked as if he were about to fade. And that would definitely not be a good thing.

"Father, I have brought the man as you requested," Artemis said, spitting out the word 'man' as if it were poison. She offered the man in question one last glare before flashing to her seat.

"Thank you, daughter," Zeus said, before his gaze fixed on the man. Before he could even speak however, said man fell to one knee.

"Hail Lord Zeus, King of Olympus," he said respectfully, head bowed. Out the corner of his eyes, he saw surprise on the faces of several of the gods, and no doubt their King was surprised as well.

"Err… Yes," Zeus agreed. "Hail me. Now then, rise. And introduce yourself to us, mortal."

Slowly, the man rose and gave them all a smile. "Has it truly been so long that you are unable to recognise me, Lord Zeus?"

The man furrowed his eyebrows, clearly not recognising him. Not that he was surprised.

"And what of you, Lord Apollo?" he asked, shifting his gaze to the Sun God, who shook his head.

Slowly, the man's gaze shifted to Poseidon and he stepped forward. "And what of you, Poseidon?" he asked in a gentle voice. "Do you truly not recognise me? Are you unable to tell who I am?"

Poseidon looked up weakly, and searched Karna's face for something. Anything. "I'm… I don't…"

"Come now, Poseidon. Look into my eyes. I know you, of all people, shall be able to tell who I am."

Poseidon slowly, ever so slowly, leaned forwards and stared into the man's eyes. He searched for something in those eyes, something familiar. And then, suddenly, Poseidon recoiled as if he'd been physically struck.

Apollo was at his side in a moment, checking on him, and the gods glared at the man. Even Zeus raised his master bolt, ready to strike him down. But they were all stopped as Poseidon's broken voice said one name.

"P… Percy?"

Nobody spoke. Nobody could at the sheer impossibility that Poseidon had just suggested. They suspected the man would just deny it, claim to be somebody else.

But he didn't. Instead he smiled softly and nodded. "Indeed, you are correct Father. I am Perseus Achilles Jackson. Son of Poseidon…" He took a deep breath. "And the Legacy of Surya, Hindu God of the Sun."

As soon as those words were spoken, the earrings on his left ear glistened slightly, and a burning sun symbol appeared over his head. There was no bow that came with Apollo's claiming, but pure light and heat.

There was silence… And then pandemonium.
